I have to say for the most part this photo expresses how Garner feels about his little brother. As much as a two year old can understand he takes care of Riley. He brings him his toys, rubs his head and kisses him, and puts his paci in for him. Overall, he is very protective and looks out for Riley. He seems to know his role.

(Excuse the chocolate on Garner's face)
On the other hand they are brothers.......
